--cli-input-json (string)
Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Indicates whether the snapshot is from an automatic backup (automated ) or was created manually (manual ).

CacheNodeType -> (string)

The name of the compute and memory capacity node type for the source cluster.

The following node types are supported by ElastiCache. Generally speaking, the current generation types provide more memory and computational power at lower cost when compared to their equivalent previous generation counterparts.

The name of the cache engine (memcached or redis ) used by the source cluster.

EngineVersion -> (string)

The version of the cache engine version that is used by the source cluster.

NumCacheNodes -> (integer)

The number of cache nodes in the source cluster.

For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 20.

PreferredAvailabilityZone -> (string)

The name of the Availability Zone in which the source cluster is located.

CacheClusterCreateTime -> (timestamp)

The date and time when the source cluster was created.

PreferredMaintenanceWindow -> (string)

Specifies the weekly time range during which maintenance on the cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period.

Valid values for ddd are:

sun

mon

tue

wed

thu

fri

sat

Example: sun:23:00-mon:01:30

TopicArn -> (string)

The Amazon Resource Name (ARN) for the topic used by the source cluster for publishing notifications.

Port -> (integer)

The port number used by each cache nodes in the source cluster.

CacheParameterGroupName -> (string)

The cache parameter group that is associated with the source cluster.

CacheSubnetGroupName -> (string)

The name of the cache subnet group associated with the source cluster.

VpcId -> (string)

The Amazon Virtual Private Cloud identifier (VPC ID) of the cache subnet group for the source cluster.

AutoMinorVersionUpgrade -> (boolean)

This parameter is currently disabled.

SnapshotRetentionLimit -> (integer)

For an automatic snapshot, the number of days for which ElastiCache retains the snapshot before deleting it.

For manual snapshots, this field reflects the SnapshotRetentionLimit for the source cluster when the snapshot was created. This field is otherwise ignored: Manual snapshots do not expire, and can only be deleted using the DeleteSnapshot operation.

Important If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off.

SnapshotWindow -> (string)

The daily time range during which ElastiCache takes daily snapshots of the source cluster.

NumNodeGroups -> (integer)

The number of node groups (shards) in this snapshot. When restoring from a snapshot, the number of node groups (shards) in the snapshot and in the restored replication group must be the same.

AutomaticFailover -> (string)

Indicates the status of Multi-AZ with automatic failover for the source Redis replication group.

Amazon ElastiCache for Redis does not support Multi-AZ with automatic failover on:

Redis versions earlier than 2.8.6.

Redis (cluster mode disabled): T1 and T2 cache node types.

Redis (cluster mode enabled): T1 node types.

NodeSnapshots -> (list)

A list of the cache nodes in the source cluster.

(structure)

Represents an individual cache node in a snapshot of a cluster.

CacheClusterId -> (string)

A unique identifier for the source cluster.

NodeGroupId -> (string)

A unique identifier for the source node group (shard).

CacheNodeId -> (string)

The cache node identifier for the node in the source cluster.

NodeGroupConfiguration -> (structure)

The configuration for the source node group (shard).

NodeGroupId -> (string)

The 4-digit id for the node group these configuration values apply to.

Slots -> (string)

A string that specifies the keyspace for a particular node group. Keyspaces range from 0 to 16,383. The string is in the format startkey-endkey .

Example: "0-3999"

ReplicaCount -> (integer)

The number of read replica nodes in this node group (shard).

PrimaryAvailabilityZone -> (string)

The Availability Zone where the primary node of this node group (shard) is launched.

ReplicaAvailabilityZones -> (list)

A list of Availability Zones to be used for the read replicas. The number of Availability Zones in this list must match the value of ReplicaCount or ReplicasPerNodeGroup if not specified.

(string)

CacheSize -> (string)

The size of the cache on the source cache node.

CacheNodeCreateTime -> (timestamp)

The date and time when the cache node was created in the source cluster.

SnapshotCreateTime -> (timestamp)

The date and time when the source node's metadata and cache data set was obtained for the snapshot.
